The specific embodiment
For making the object of the invention, technical scheme and advantage more cheer and bright, through the specific embodiment shown in the accompanying drawing the present invention is described below.But should be appreciated that these descriptions are exemplary, and do not really want to limit scope of the present invention.In addition, in following explanation, omitted to the description of known configurations, to avoid unnecessarily obscuring notion of the present invention with technology.
Layer structural representation according to the embodiment of the invention shown in the drawings.These figure draw in proportion, wherein for purpose clearly, have amplified some details, and possibly omit some details.The shape of the various zones shown in the figure, layer and the relative size between them, position relation only are exemplary; Maybe be because manufacturing tolerance or technical limitations and deviation to some extent in the reality, and those skilled in the art according to reality required can design in addition have difformity, the regions/layers of size, relative position.
Extrusion die of the present invention is used for cooperating to form the main part of extruding puffing machine with the screw rod extrusion device.Specifically, it is identical substantially with the sleeve outer diameter of screw rod extrusion device that the sleeve of extrusion die forms usually, makes the material channel of the two to dock.Like this, the material that comes out from the screw rod extrusion device can get into the material channel of extrusion die smoothly.The screw rod extrusion device forms the screw rod that laterally arranges; Each screw rod rotates with identical rotating speed in the same way; Make material in sleeve, constantly push ahead along with the rotation in the same way of screw rod, through heat and the motion of the flight on the screw rod that sleeve provides, material is by constantly shearing, kneading, fusion; Be extruded simultaneously and pushing ahead, can material be processed into the albumen molten mass that tentatively has the filamentary fibers structure.
But fibre length, the viscosity of the albumen molten mass through screw rod extrusion device processing are limited, can not be suitable for the demand of greater protein goods.Therefore, need to adopt extrusion die that the wire-drawing protein that begins to take shape is carried out wire drawing and handle, so that the length of its filamentary fibers is longer, viscosity is higher, and fiber alignment is more even.Special, for being the technology of main material production wire-drawing protein with the high temperature dregs of rice, existing extrusion die is because limited length, simple in structure can not be applicable to this special process.
Than prior art, extrusion die of the present invention can carry out wire drawing more completely to be handled the wire-drawing protein that the processing of screw rod extrusion device begins to take shape, thereby is particularly useful for the technology that the high temperature dregs of rice are the main material production wire-drawing protein.But, do not represent the present invention to be restricted to this, also be that extrusion die of the present invention also goes for known wire-drawing protein or histone production technology, and have better wire drawing effect.
In addition, the screw rod extrusion device that cooperates with extrusion die of the present invention can be the screw rod extrusion device of any known or UNKNOWN TYPE, for example single screw rod, twin-screw or three screw rod extrusion devices.
Fig. 2 has shown the extrusion die that is used for extruding puffing machine of the preferred embodiment of the present invention.
As shown in Figure 2, the extrusion die of present embodiment comprises following part: manifold 1, reorganization chamber 2, compression chamber 3, extruding cavity 4 and discharging mouth 5.
Manifold 1 is used for the material channel that receives material and be transported to the back.
Manifold 1 docks with the screw rod extrusion device, and receives the material of preparatory processing from the screw rod extrusion device, and the material of this preparatory processing still be the filamentary fibers of relatively lacking.
Fig. 3 a and 3b have shown the manifold structure chart of preferred embodiment, and wherein Fig. 3 a shows the front view of manifold, and Fig. 3 b shows the side view of manifold, and Fig. 3 c has shown the material form sketch map in the manifold.
Shown in Fig. 3 a, manifold 1 comprises three functional sections along the material direction of advance: reception cavity 101, relief frame 102 and slowly-releasing chamber 103.
Relief frame is a passage aisle with the material afflux of screw rod output, and material changes rectilinear motion into by spiral motion.In addition, relief frame is the extruding of major diameter material to make that through short-range extruding the key between the material molecule is better affine by the circular material of minor diameter.Simultaneously, through this short distance supercharging, make the material situation that pressure discharges in the slowly-releasing chamber of back progressively discharge, thereby be convenient to form filamentary fibers, shown in Fig. 3 c front end.
The aperture of relief frame is about 6～100mm, and the squeeze pressure of generation is approximately 1～50kg/cm
2, preferably produce 3～12.5kg/cm
2Squeeze pressure.The length of relief frame is about 6～200mm, and is preferred, and the ratio of the screw diameter of relief frame length/screw rod extrusion device is arranged between about 0.2～2, preferably is set to 0.5.
Slowly-releasing chamber 103 forms the passage that the aperture progressively increases or gradient increases, and is used for discharging gradually material pressure.
Conical cavity is preferably adopted in the slowly-releasing chamber, but is not restricted to this, but as long as the aperture progressively or the passage that increases of gradient can both be suitable for, and can increase slope according to the aperture in the suitable adjustment slowly-releasing chamber of actual conditions.Material can reduce extruding force that material is applied when the slowly-releasing chamber gradually, makes that closely affine material together slowly discharges, and is convenient to the easier formation silk-like proteins of material, shown in Fig. 3 c rear end.Otherwise if steadily do not discharge material pressure through the slowly-releasing chamber, the unexpected release pressure of meeting caused material to be blown when material got into the passage that diameter is bigger at the back, was difficult to form thread.
The extruding force that the slowly-releasing chamber applies material does not have strict restriction, so long as on the extruding force basis of relief frame, reduce gradually or gradient reduces, it is just passable to reach the purpose that material is slowly discharged.
More than introduced the structure of the manifold of the embodiment of the invention.Among the present invention, the length of manifold 1 is about 10mm～1000mm, preferably is set to 240mm.Manifold is connected through bolt or other connector by 1 joint or more piece flange usually.As a whole, the end that manifold is connected with the screw rod extrusion device is intersected by two passages (under the double screw extruder situation) and compiles a passage (relief frame) that the aperture is less, makes the passage aperture progressively be amplified to consistent with the chamber passage of recombinating (slowly-releasing chamber) again.
Fig. 4 has shown the material form sketch map in the reorganization chamber.
After the extruding force of material in the slowly-releasing chamber was discharged into to a certain degree, the fibre structure that gets into the material in reorganization chamber still presented random arrangement in a large number.In constant and relatively large reorganization chamber, aperture, the material melt of silk-like proteins state is steadily discharged under this constant extruding force effect, protein molecule is bonding no longer tight in the material.Simultaneously, each other bonding again and align between the loose relatively protein molecule under the forward thrust effect, thus begin to take shape filamentary fibers with length.
In the present embodiment, the spiral external diameter of the screw rod extrusion device that cooperates with extrusion die is big more, and the aperture in reorganization chamber is big more accordingly.As a rule, the ratio of the spiral external diameter (usually in about 20～276mm scope) of the aperture in reorganization chamber and the screw rod of front is controlled in 0.3～1.5 scope, preferably is set to 0.7.In a preferred embodiment, the aperture in reorganization chamber is in 10～150mm scope, and length is in 100～6000mm scope, and preferred length is 1000mm.
As shown in Figure 4, in the reorganization chamber, be in filamentary fibers that the protein molecule of looser tacky state constitutes and bend to roughly U type gradually along direction of advance under the frictional force effect of thrust and the vias inner walls of material in the back.
Fig. 5 has shown the material form sketch map in the compression chamber.
After material steadily discharged in the reorganization chamber, material began to take shape the wire drawing state than the long fibre structure.In the littler compression chamber in aperture; Increased the extruding force that imposes on material; Under the shape limits effect of material thrust and cavity inner wall, the filamentary fibers that bends to the U type progressively forms little U type (the U type that degree of crook is bigger) along direction of advance to material in the back, and filamentary fibers rate of curving under the extruding force effect is increasing; The long filament shape fiber that final extruding wire drawing becomes to have length, as shown in Figure 5.
The aperture of compression chamber is littler than the aperture in reorganization chamber, is beneficial to the filamentary fibers that bends to large U type is bent to little U type.The aperture of compression chamber can be set to than the littler steady state value in reorganization lumen pore footpath, can be set to also that the aperture reduces gradually or gradient reduces.As shown in Figure 2, the compression chamber among the present invention can form for 1 joint integral sleeve, perhaps is formed by connecting through flange, bolt in more piece segmentation sleeve.
In the present embodiment, the length of compression chamber is set to about 10mm～1000mm, and the passage aperture is about 10mm～100mm.
Fig. 6 has shown the material form sketch map in the extruding cavity.
Extruding cavity 4 is connected to compression chamber and has the aperture littler than compression chamber, is used for material is further pushed wire drawing, and material steadily is transported to the discharging mouth.Specifically, the effect of extruding cavity is to make that filamentary fibers rate of curving under the shape limits of extruding force that increases and extruding cavity inwall is increasing, finally extrudes the long filament shape fiber that wire drawing becomes to have length, and is as shown in Figure 6.The aperture of extruding cavity can be set to than the littler steady state value in compression lumen pore footpath, also can be set to reduce gradually or gradient reduces.
In the present embodiment, the length of extruding cavity is about 10mm～1000mm, can form for 1 joint integral sleeve, perhaps is formed by connecting through flange, bolt in more piece segmentation sleeve.Extruding cavity the passage aperture be 10mm～100mm, its main effect is that a melt material steadily is transported to the discharging mouth.
What should explain is that extruding cavity is not necessary among the present invention.As a rule, the total length of compression chamber and extruding cavity is long more, and the wire vent effect is good more, but wire vent speed is slow more, can influence speed of production; Otherwise total length is short more, and wire vent speed is fast more, but the wire vent effect is poor more.Therefore, can select to be provided with or not to be provided with extruding cavity, perhaps select one or more snippets extruding cavity is set, perhaps adjust the total length of compression chamber and extruding cavity according to the material situation and the process requirements of reality.Among the present invention, the total length of compression chamber and extruding cavity is arranged in about 200～6000mm scope, preferably is set to 2000mm.
Referring to Fig. 2, the discharging mouth is arranged on the end of extrusion die, has littler aperture, and it mainly acts on is pressure and the shape that guarantees material outlet, is convenient to be extruded into silk.
The effect of discharging mouth is to make the material that forms long filament shape fiber be extruded into silk under the inner wall shape restriction of thrust and the discharging opening of material in the back, becomes final wire-drawing protein product.
Among the present invention, the aperture of discharging opening is arranged between 0.1～0.5 with the ratio of the screw diameter of the screw rod extrusion device that cooperates, and preferably is set to 0.3.The aperture of discharging opening is excessive, possibly cause material can not become silk, and the aperture is too small, and then possibly cause can not extruded material.In a specific embodiment, the discharging opening aperture is set to 3～500mm, optional 100mm or the 200mm of being set to, and length is set to about 10mm～1000mm.In addition, the discharging mouth can be set to single hole or porous.Under the porous situation, total cross-sectional area of porous equals about 1.25 times of single hole area.
Among the present invention, the sleeve of extrusion die is provided with inlet and liquid outlet, is used for the temperature that input media is regulated extrusion die, and medium for example comprises gas or liquid such as high-temperature steam, cooling water.The operating temperature of extrusion die of the present invention is between about 60～200 degree, preferably between about 80～120 degree.
Among the present invention, the draw ratio of extrusion die is arranged between about 4-64, preferably is arranged between about 4-40.For example, in some specific embodiment, can be set to numerical value such as 4,8,28,36,40,48,64.The draw ratio of extrusion die is different, and the final material form that forms is different, and the product form of consequent wire-drawing protein is also different, thereby is applicable to various demand.
As stated, through extrusion die of the present invention, can the wire-drawing protein that have than staple length be formed the wire-drawing protein that has than long fiber length, and viscosity is higher.This long filament shape fiber is cut into the sarconeme shape fiber according to various needs in use, and then is processed into the product of different shape easily.
